EDWARD E. DULIER, OF LONDON, ENGLAND.

APPARATUS FOR REMOVING IMPURITIES FROM SMOKE.

SPECIFICATION forming part of Letters Patent No. 509,798, dated November 28,1893.

Application filed May 25, 1893.

To all whom it may concern:

Be it known that I, EDWARD EUGENE DU- LIER, a citizen of Belgium, residing at No. 27 Sloane Gardens, Chelsea, London, England, have invented certain new and useful Apparatus for Removing Impuritiesfrom Smoke, of which the following is a specification.

In the specification of my Patent No. 490,550 dated January 24:, 1893, I have described means of removing impurities from smoke by mixing the smoke with steam and then cool-.

, Figure 1 is a vertical'section and Fig. 2 is a sectional plan of apparatus according to my present invention for causing deposit of carbonaceous, sulphurous and other impurities from the productsof combustion of a furnace or set of furnaces.

O is the fine from the furnace or set of furnaces. Between it and the chimney shaft S, I construct a passage in the form of an inverted U, the limbs of which are separated by a partition P. At the bottom of they ascending limb A I place a steam pipe B perforated with numerous holes along its upper side. At the top of the descending limb D I place a water pipe Y perforated with numerous holes along its lower side. v

The products of combustion ascend the limb A becoming mixed with the steam from the pipe B which by ejector action promotes their flow. After passing over the crown of the partition P they receive a shower of water from the pipe which condenses the steam and causes deposit of the carbonaceous, sulphurous and other impurities from the products of combustion, which then pass away Serial No. 475.475. (No model.)

by the shaft S comparatively freed from black and noxious matters. The deposited matters collect with the water at the bottom of the limb D, whence they are carried away bya drain E.

The partition P is preferably made double as shown, so that there is little conduction of heat from A to D. As the gaseous fuel is in the descending limb I) colder and therefore denser than in the ascending limbA, the preponderance of theformer adds to theforce of the chimney draft. Byincreasing the height of the limbs A and D this preponderance may be made sufficient to produce the necessary draft without requiring a chimney for that purpose, especially as the ascending steam in the one limb and the descending water in the other limb aid in prom ting the flow of the gaseous fluid.

Having thus described the nature 'of this invention, and the best means I know for can rying the same into practical effect,Iclaim- An apparatus for removingimpurities from smoke, the same consisting of a continuous passage made'in the form of an inverted U, the vertical walls thereof being separated by a partition having the form of an inverted U, a steam-pipe arranged in the lower part of the ascending branch of said passage and provided with steam exits which discharge ED WARD.
